An ordinarysection of hose or flexiroo 5p,iiXed to its upper end. A cut-off valve 14 is ble tube 38 is connectedat one end tothe end located in this inlet-pipe 13. An outlet or of thepipe 37 and at the other end to a pipe 39, that is connected to thecenter of the distributing-pipe 31.

A pair of handles 40, provided with suitable standards 41, extendrearwardly from the U-shaped portion 2 and serve as means for moving thesteam-cooker from one point to another.

The operation is as follows: The Water-reservoir 12 being filled withWater through the funnel and pipe 13, a portion of the water within saidreservoir will pass through the pipe 16 into the steam-generatingreceptacle 10 within the boiler 1 The steam-generating receptacle 10being in approximately the same plane as is the Water-reservoir 12, thewater Within said steam-generating receptacle 10 will rise to a point ashigh as is the Water Within the water-reservoir 12. As the Water withinthe steam-generating receptacle becomes heated bythe fire Within thefire-box of the boiler 1, steam will be generated within said receptacle10, and, as it increases in volume, will open the automatic valve 24. Ifit is desired to cook the food placed in the receptacles 30, the valve2G must be closed and the Valve 35 opened. The steam thus generated willpass through the automatic cutoff valve 24, through the pipes 34 and 37,through the flexible pipe 3S, into the distributing-pipe 31. From hereit is discharged through the nozzles 32, that are located within thereceptacles 30, thus steaming and cooking the food, as desired.

Should it be desired to cook or steam a quantity of food in a singlereceptacle, such as 42, the lower end of the hose or flexible tube 29 ispositioned within said receptacle 42, the valve 28 in the pipe 27opened, the valve 26 in the pipe 25 opened, the valve 35 in the pipe 34closed, and the valve 22 in the pipe 19 closed. This being done, thesteam will pass through the automatic cutoff valye 24, through the pipe25 into the steam-reservoir 18, from thence through the pipe 27 andiiexible pipe 29 into the receptacle 42, in which the food to be cookedor steamed is deposited.

If it is desired to cook food placed in the receptacles 30 and also foodin the receptacle 42, the valves 35, 26, and 28 are opened and the valve22 closed. Thus steam will be passed through. the various pipes andconnections into the receptacles 30 and the receptacle 42. By themanipulation of the cut-off valves 33 in the nozzles 32 steam can bepassed through any one or all of said nozzles 32. If desired, the upperend of the flexible tube 3S can be disconnected from the eiid of thepipe 37` and the upper end of the ilexible tube or hose 29 positionedupon the end of said pipe 37. By nowY closing the valve 2G the steamwill be passed through the pipe 34, pipe 37,

' and fiexible tube or hose 29 into the receptacle 42.

Vhen the valves 35 and 28 are closed, any steam that maybe generated orin the steamreservoir 18 will pass through the pipe 19, the valve 22having previously been opened, through the pipe 21 and into thewater-reservoir 12, there to condense. Should at any time it be foundadvisable to wash out or cleanse the steam-generating receptacle andvarious connections, the valve 2G and the faucet 15 are opened. A supplyof water now being introduced through the pipe 27 into thesteam-reservoir 18 will pass from said reservoir through the pipe 25,through the automatic cut-off valve 24, previously opened, through thepipe 23 and steam-generating receptacle 10, through the pipe 17 into thewater-reservoir 12 and out through the faucet 15, thereby thoroughlycleansing said receptacles and connections.

The annular flange 11 on the steam-generating receptacle 10 tends toretain the heat and flame emanating from the lire in the nrebox of theboiler 1 and more thoroughlyheat the Water within said steam-generatingreceptacle 10.

By grasping the handles 40 and raising the standards 41 free from theground the entire cooker can be easily and quickly moved from one pointto another.

Thus will be seen how I have constructed a steam-cooker that is simpleand inexpensive in construction, easily operated, and capable of beingmoved from one point to another to facilitate the cooking of the variouskinds of food.

The combination, with a steam-generator and its supports, of a mainsteam-discharge pipe 23, the automatic valve 24 connected to said pipe,a smaller steam-discharge pipe 25 connected directly to said valve, avalve 2G applied to said smaller pipe, connections with the latter forconducting steam therefrom to a cooking utensil as 42, an additionalsteamdischarge pipe 34 also connected directly to the said automaticvalve, a valve 35 applied to the pipe last mentioned, and connectionsfor conveying steam from said last-mentioned pipe to an additionalcooking utensil or a series of utensils, substantially as and for thepurposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
